Umgaqo womatshini wempompo yeoli
Ioyile yokufunxa uxinzelelo lweoyile
I-oyile yokufunxa kunye noxinzelelo lwe-oyile yempompo yokutofa igqitywe yintshukumo yokubuyisela i-plunger kwi-sleeve ye-plunger. Xa i-plunger ikwindawo esezantsi, imingxuma emibini yeoli kumkhono we-plunger iyavulwa, kwaye umngxuma ongaphakathi womkhono we-plunger unxibelelana ne-oyile ye-oyile kumzimba wempompo, kwaye i-fuel izaliswe ngokukhawuleza ngegumbi leoli. Xa i-CAM iphumla kwi-roller ye-roller body, i-plunger iphakama. Shenxisela phezulu ukusuka ekuqaleni kweplunger de umngxuma we-oyile uvalwe bubuso obungasentla beplunger. Ngeli xesha lexesha, ngenxa yokuhamba kwe-plunger, i-fuel ikhutshwe ngaphandle kwegumbi leoli kwaye igeleza kwi-oil passage. Ke oku kunyuswa kubizwa ngokuba yi-pretravel. Xa i-plunger ivala umngxuma we-oyile, inkqubo yokucinezela i-oyile iqala. Xa i-plunger inyuka, uxinzelelo lwe-oyile kwigumbi le-oyile luyenyuka ngokukhawuleza. Xa uxinzelelo ludlula i-spring spring ye-valve ye-oyile kunye noxinzelelo lwe-oyile ephezulu, i-valve yeoli ikhutshwe, kwaye i-fuel icinezelwe kwipayipi yeoli kwaye ithunyelwe kwi-injector ye-fuel.
Ixesha apho umngxuma wokungena kwe-oyile kumkhono we-plunger uvalwe ngokupheleleyo bubuso obungasentla be-plunger ibizwa ngokuba yindawo yokuqalisa i-oyile yethiyori. Xa i-plunger iqhubeka ihambela phezulu, ukunikezelwa kweoyile kuyaqhubeka, kwaye inkqubo yoxinzelelo lwe-oyile iyaqhubeka de i-helical bevel kwiplunger ivule umngxuma weoyile. Xa uvula umngxuma we-oyile, i-oyile yoxinzelelo oluphezulu ibaleka isuka kwigumbi le-oyile idlula kwi-longitudinal groove kwi-plunger kunye nomngxuma wokubuyiswa kwe-oyile kumkhono we-plunger ukuya kwipaseji yeoli kumzimba wempompo. Ngeli xesha, uxinzelelo lweoyile yegumbi leoyile ye-plunger yehla ngokukhawuleza, ivalve yokukhupha ioyile ibuyela kwisitulo sevalvu phantsi koxinzelelo lweoyile entwasahlobo kunye netyhubhu yoxinzelelo oluphezulu, kwaye i-injector iyayeka kwangoko ukutshiza ioyile. Ngeli xesha, nangona i-plunger iqhubeka nokunyuka, ukunikezelwa kweoyile kuphelisiwe. Umzuzu xa umngxuma wokubuya kwe-oyile kumkhono weplunger uvulwa kwicala le-bevel leplunger ubizwa ngokuba yindawo yokuphela kobonelelo lweoyile. Kuyo yonke inkqubo yokunyuka kwe-plunger, kuphela indawo ephakathi ye-stroke yinkqubo yoxinzelelo lwe-oyile, ebizwa ngokuba yi-stroke esebenzayo ye-plunger.
Ulawulo lwamafutha
Ukuze kuhlangatyezwane neemfuno zomthwalo we-injini ye-diesel, ukunikezelwa kwepetroli yempompo ye-injection ye-fuel kufuneka ikwazi ukulungelelanisa phakathi koluhlu lwe-fuel unikezelo olupheleleyo (umthwalo ogcweleyo) kwi-zero fuel supply (stop). Ukulungelelaniswa kokunikezelwa kwamafutha kuqondwa ngentonga yezinyo kunye nomkhono ojikelezayo ukwenza zonke iiplungers zepompo yokutofa kwe-fuel zijikeleze ngaxeshanye. Xa i-plunger ijikeleza, ixesha lokuqala lokunikezelwa kwe-oyile alitshintshi, kwaye ixesha lokuphela kwe-oyile litshintshile ngenxa yokutshintsha kwendawo yokubuyisela i-oyile yomngxuma we-plunger kwicala le-bevel ye-plunger. Nge-Angle eyahlukileyo yokujikeleza kwe-plunger, i-stroke esebenzayo ye-plunger iyahluka, kwaye ukunikezelwa kweoli kuyatshintshwa.
Okukhona i-Engile yokujikeleza kweplunger yokungabikho kwe-oyile inqanaba loku-1, kokukhona umgama omkhulu phakathi kobuso besiphelo esiphezulu se-plunger kunye ne-hypotenuse ye-oyile yokubuyisela umngxuma wesingxobo seplagi evulekileyo, kunye nokubonelelwa okukhulu kwe-oyile. Ukuba i-Angle yokujikeleza i-plunger incinci, ukunqunyulwa kwe-oyile kuqala kwangethuba kwaye ukunikezelwa kwe-oyile kuncinci. Xa injini ye-diesel imisiwe, i-oyile kufuneka inqunyulwe. Ngesi sizathu, i-longitudinal groove kwi-plunger inokujikwa kumngxuma we-oyile wokubuyela ngqo ngokuchasene nomkhono weplunger. Ngeli xesha, kuyo yonke i-stroke ye-plunger, i-fuel kwi-sleeve ye-plunger iye yabuyela kumjelo we-oyile ngokusebenzisa i-longitudinal groove kunye ne-oil return hole, akukho nkqubo yoxinzelelo lwe-oyile, ngoko ke ukunikezelwa kweoli kufana ne-zero. Xa i-plunger ijikeleza, ixesha lokutshintsha indawo yokuphela kwe-oyile isetyenziselwa ukulungelelanisa unikezelo lwe-oyile, olubizwa ngokuba yi-oil supply end point adjustment method.
Ubonelelo lweoyile yempompo yeoli kufuneka lufezekise iimfuno zenjini yedizili kwiimeko ezahlukeneyo zokusebenza, ngokweemfuno zenjini yedizili, impompo yeoli kufuneka iqinisekise ukuba unikezelo lweoyile yesilinda nganye luqala ngaxeshanye, oko kukuthi, ukuhanjiswa kweoyile kwangaphambili I-Angle iyahambelana, kufuneka iqinisekise ukuba ixesha lonikezelo lweoyile liyafana, kwaye unikezelo lweoyile kufuneka luqale ngokukhawuleza, luyeke, lunqande i-oyile ngokukhawuleza kwaye luthontsize. Ngokuxhomekeke kwifom yegumbi lokutsha kunye nendlela yokwenza umxube, ipompo yeoli kufuneka inike i-fuel ngoxinzelelo olwaneleyo kwi-injector ukuqinisekisa umgangatho omhle we-atomization.
